Zebra Mayan cichlid

Where they come from

Zebra Mayan cichlids (Mayaheros zebra) come from Central America, mostly around Guatemala and southern Mexico. They show up in lakes, rivers, and slower backwaters where there are rocks, roots, and plenty of little critters to hunt. That wild background explains a lot: they like structure, they like to dig, and they do not appreciate pushy tankmates right up in their face.

Setting up their tank

Think "rocky shoreline with hiding spots" and you are pretty close. Give them a footprint more than height. A single adult can work in a 55 gallon, but if you are doing a pair or any kind of community, I would not bother with less than a 75. They get big, and they act bigger than their length.

• Tank size: 55 gallons for one, 75+ gallons for a pair or with tankmates
• Temp: 75-82F (I keep mine around 78-80F)
• pH: neutral to slightly alkaline (around 7.0-8.0 is fine)
• Hardness: moderate is great; they are usually not fussy if things are stable
• Flow and oxygen: moderate flow and good surface agitation keep them happier and less prone to issues

For substrate, sand is my pick. They sift and dig, and sand keeps them from scraping their mouths when they get into "construction mode." If you use gravel, go smooth and not too sharp.

Decor-wise, I like a few solid rock piles and some driftwood to break lines of sight. If you want plants, choose tough stuff or stuff you can attach to rocks (Anubias, Java fern). Anything rooted in the sand is basically a snack or a landscaping project.

What to feed them

They eat like classic Central American cichlids: a mix of meaty foods, pellets, and whatever they can bully out of the environment. In my tanks they do best on a good quality cichlid pellet as the staple, then I rotate frozen foods to keep condition and color up.

• Staple: quality pellets (medium to large cichlid pellet depending on fish size)
• Frozen rotation: krill, mysis, brine shrimp, chopped prawns, bloodworms as an occasional treat
• Fresh add-ons: pieces of white fish or shrimp occasionally (rinse well)
• Greens/fiber: spirulina-based pellets or a little blanched zucchini now and then helps digestion

Feeding schedule is simple: once a day for adults, twice a day for growing juveniles. Keep portions tight. If you see thick "cichlid shoulders" turning into a beer belly, dial it back. These guys will always act like they are starving.

How they behave and who they get along with

Zebra Mayan cichlids have that confident, territorial vibe. Not always nonstop aggression, but they are opinionated, and they like owning a chunk of the tank. The bigger they get, the more you notice it.

With tankmates, you want fish that can handle themselves without being total psychopaths. Medium-large, sturdy species tend to work. Small fish will get eaten, and timid fish will get stressed into sickness.

• Good matches (in the right tank): other robust Central/South American cichlids of similar size, larger barbs, bigger livebearers in hard water setups, armored catfish like larger plecos
• Use caution: other bottom dwellers (they compete for territory), slow fancy fish, long-finned fish
• Avoid: tiny tetras, guppies, shrimp, snails you care about, anything very shy or delicate

If you are keeping more than one, watch the dynamic. A bonded pair can be solid, but two random adults can turn into a nonstop beatdown. I have had the best luck growing a group of juveniles and letting a pair form, then moving everyone else out.

Breeding tips

If you end up with a true pair, they are usually willing breeders. You will see cleaning behavior on a flat rock or in a dug-out pit, then the tank suddenly becomes "their" tank.

• Give them a flat rock or a smooth tile for spawning
• Keep water changes steady; they often spawn after a big change
• Have a plan for tankmates - a breeding pair will run the whole aquarium
• Feed a bit heavier leading up to spawning, then keep it clean and consistent

Fry are not hard if the parents are good. In many cases the parents do most of the work. If you pull fry, start with freshly hatched brine shrimp and fine crushed foods, and stay on top of water changes because growth plus heavy feeding gets messy fast.

Common problems to watch for

Most of the issues I see with Mayaheros zebra come from three things: cramped tanks, dirty water from heavy feeding, and stress from bad tankmate choices. Fix those and they are pretty hardy fish.

• Hole-in-the-head and chronic pitting: often tied to long-term water quality issues and poor diet variety
• Bloat/constipation: usually from overfeeding rich foods or not enough fiber
• Fin damage: aggression, especially in smaller tanks or with too few hiding spots
• Ich: tends to show up after new fish additions or temperature swings
• Mouth injuries: from digging in sharp gravel or ramming decor during fights

My routine that keeps them looking good: weekly water changes (bigger if you feed heavy), vacuum the areas where food collects, rinse filter media in old tank water, and do not let nitrate creep up forever. They can handle a lot, but they look and act better when the tank is kept simple and clean.
